i With these and other objects in view as will appear hereinafter, my invention consists of certain novel features of construction, combination and arran ement of parts and portions as will be hereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompanying drawings and to the characters of reference thereon which form a part of this application, in which:

Figure l is a fragmentary perspective view of a building incorporating my invention in the wall, Hoor, roof and parapet wall thereof in one form, Fig. 2 is a fragmentary sectional view thereof in plan showing the construction of a wall thereof in one form, Fig. 3 is a fragmentary sectional view in elevation showing the construction of the floor and roof thereof in one form, Fig. 4 is a fragmentary sectional elevational view taken through 4 4 of Fig. 1 showing the construction of the parapet wall and its relation to the main wall and the roof thereof in one form, Fig. 5 is a fragmentary perspective view showing the upper ends of one of the wall units, shown in Fig. 1, and showing particularly the means of securing the separate units lof the wall together, Fig. 6 is a fra i entary perspective view of the upper en of the wall units in a slightly modified form of construction, Figs. 7 and 8 are fragmentary perspective views of the up- `ends of the units for pouring the concrete Stringer in place for securing the upper ends of the wall units together.

Similar characters of reference refer to similar parts vand portions throughout the several views of the drawings.

The wall portion of my new concrete construction consists primarily of a foundation 1, vertical1wall units 2, sealing members or strips 3, wall unit tie members 4, and hori, zontal girders or stringers 5, as shown best in Fig. 1.

The foundation l is preferably made of ordinary concrete and is cast or molded with a longitudinal groove in its upper face, said groove being spaced from the inner and outer sides of the. foundation.- This foundation is also provided with a supporting ledge at its inner side and below the upper face of the foundation for supporting the floor slabs, as will be described hereafter. In the foundation Wall, and on the inner side thereof, are imbeddedbase nailing strips 6.

The wall units 2 consist preferably of two vertical wall members 2a, as shown best in Fig. 2. These wall members 2a are channel shape in cross section and are positioned with the edges of their flanges in abutting relation forming substantially hollow columns or wall members with vertical voids.l The outer sides of these channel members form respectively the outer and inner faces of the walll and are alined substantially with the outer face of the foundation and the inner facel thereof above the ledge.

The lower ends of these wall units 2 are formed preferably of tenons 2b, which extend into the groove 1a for fixedly positioning the lower ends of the wall units relative to the foundation. f

In Fig. 9 of the drawings, I have shown a slightly modified form of construction of the lower end of the wall units. In this modified form, I have provided pins 7 a, preferably of metal. which are inserted into the lower ends of the flanges of the channel members 2d and which extend into the groove 1.a of the foundation. rI`he ends of. the pins 7, which extend downwardly are imbedded in a gro'ut 8, with which the groove la is filled.

In order to seal the joints between two adjacent wall units, I place weather strips such as water-proof building` paper 3, between the abutting edges of the anges of the channel members of each unit, such weather paper bein of suicient Width as to extend over the a utting edges of the flanges of theadja- 'cent sides of adjacent wall units as shown best in Fig. 2, so as to prevent moisture from passing through the wall at the 'oints.

Where window openings are esired only short wall units 2 and 2 are placed below and above the desired openings, as shown in Fig. 1. The ends of the units may be closed by sills 25 and lintels 26 of concrete as shown. Door openings are -similarly formed. In the points between the channel members 2, forming the sides of the openings, may be secured anchors 27 to which window and doors casings may be secured.

The upper ends of the Hanges of the channel members are provided with transverse slots 2c, into which extend the legs 4a of inverted U-shape securing or tie. members 4. These tie members may be made of sheet metal and rest with the portions thereof, connecting the legs 4a, upon the upper ends of said flanges, as shown in Figs. 5 and 6. Thus the upper ends of the two channel members making up one wall unit are secured together.

In the modified structure shown in Fig. 7,

. the channel members are secured together by a diderent means, this means consisting of pins 9 inserted into the upper ends of the flanges of the ch'annel members, and a wire 10 securing such ends together. It will be noted that the wire 10 may extend around all of the pins in the adjacent flanges of adjacent wall units as shown in Fig. 7.

In the modified structure shown in Fig. 8, the pins are eliminated and instead there are imbedded into the channel members, in place of pins, wires 11, which are secured together, for securing together, not only the two channel members of each unit but also adjacent wall units.

Over the upper ends of the wall units is cast in place a concrete cap 5, which forms a string-er for the upper portion of the wall, for

rigidly tyingadjacent wall units together, as

well :1s-tying the separate members of each unit together. It will be noted that in Figs. 1 and 5, of the drawings. the webs of the channel members 2a extend above the flanges thereof and form the lower portions of such .st-ringer as well as form a part of the mold for such Stringer.

In the modified structure shown in Figs. 6, '7 and 8. these upwardly extending webs are eliminated, and in these instances, the whole of the strngers rest upon the upper ends of the wall units.

If it is desired to prevent the concrete forming the stringers 5 from running into the hollow wall members, in order to retain the voids therein, there may be placed at the upper end of such units wire mesh 12 and building paper 13, as shown best in Fig.

In of the drawings, I ha'vevshown a l vmold or form for pouring or fastening the stringer 5 in place. This form consists of boards 14, placed in spaced apart relation at the inner and outer sides of the wall units so that the same extend above the wall units. These form boards are secured to the upper ends of the wall units by bolts 15, which rest in transverse slots 2d in the upper ends of the webs of the channel members 2a, and which bolts extend throughsaid board. The upper edges of the form boards may be secured t0- gether by tie strips 16. If it is desired to form a ledge 5a, at the inner side of the stringers 5, a strip 17 may be secured tothe upper portion of the inner form board 14, as shown in Fig. 10.

Floor andvroof structure of mynew building construction are substantially the same and consist substantially of relatively narrow slabs 18, which are pre-cast' of reinforced concrete, as indicated on the channel members of the wall units. These slabsconsist of slab portions 18a,having upwardly extending webs 186, which are spaced from'each otherand inwardly from the edges of the slab portion, forming longitudinal channels between the webs of-each slab and other longitudinal channels between adjacentl webs of adjacent slabs, as shown best in Fig. 3, the latter chanvchannels or beams and also throu h the webs formin such channels.' The sla s may be also remforced by longitudinally extending reinforcing rods 20 within such channels, as shown `in Fi- 3. Simultaneously with the pouring4 of t e concrete in the channels between adjacent slabs, concrete is also poured between the ends of the slabs and the inner sides of the foundation 1, or Stringer 5 above the ledges, for securely tying the iioors .roof to the wall. If it is desired to` prevent the concrete from flowing into the other channels of the slabs, there may be placed over the ,y

ends of such channels wire `mesh 21, and building paper 22, as shown in Fig. 1. The floor or roof boards 23, or the strips or stringers to which the same are secured, may be placed directly upon the upper edges of the webs of the slabs as'shown.

The parapet wall of my new building construction consists preferably also of a pair of pre-cast concrete channel members 23, which are positioned horizontally with their channel portions adjacent each other. These channel members are, however, s aced apart the desired distance, primarily or forming a space at the lower portion ofthe parapet wall for ventilation purposes. The outer channel member in this instance rests upon the Stringer 5, while the inner channel member 23 rests upon the ends Vof the upper edges of the webs of the slabs 18. Upon the upper flanges of the channel members 23, is placed a suitable cap .24, for sealing the space between the upper flanges of the channel members as shown in Figs. -1 and 4. In the case of the securing of the slabs 18 to the wall or the Stringer 5, the channels between the webs of each slab are left open so that an air passage may be provided between the space in the parapet wall and such channels in the both of the channel members 23, may be pro- `roof for ventilation purposes. A In eithery or y vided openings 23a, so as to permit communication with the atmosphere of the space in the parapet wall to facllitate the circulation.A Y

Over these openings vmay' be placed a suitable wire mesh vor grating 24, to exclude matter which might clog the air passages. V -Though I have shown Iand described a particular construction, combination and arrangement ofparts and portions of my new building construction, and though I have shown certain modifications thereof, I do not wish tobe ylimited to this particular construction, combination and arrangement nor to the modifications, but 'desire to include in the scope of `my invention, the construction, combination and arrangement substantially as set forth in the appended claims.
